10. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Synovial Joints  Articulating bones are separated by a joint cavity

12. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Features of Synovial Joints  Articular cartilage covers the ends of bones  A fibrous articular capsule encloses joint surfaces  A joint cavity is filled with  Ligaments

13. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Structures Associated with the Synovial Joint  Bursae—flattened fibrous sacs  Tendon sheath

17. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Inflammatory Conditions Associated with Joints  Bursitis  Tendonitis  Arthritis

18. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Clinical Forms of Arthritis  Osteoarthritis  Rheumatoid arthritis  An autoimmune disease

19. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Clinical Forms of Arthritis  Gouty arthritis

20. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Developmental Aspects of the Skeletal System  At birth, the skull bones are incomplete  Bones are joined by fibrous membranes  Fontanels are completely replaced with bone

28. Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings Skeletal Changes Throughout Life  Osteoporosis  Bone-thinning disease afflicting  Disease makes bones fragile and bones can easily fracture  Vertebral collapse results in kyphosis  Estrogen aids in health and normal density of a female skeleton
